. HEATING srrovn.

Application filed May 1,

g 1 all whom it may concern.

Be it known that we, HENRY C. HAMILTON and GEORGE W. BAILEY, citizens ofthe United States, residing at Spokane, in Spokane County and State ofWVashington, have invented certain new and useful Improvements inHeating Stoves, of which the following is a specification.

Our present invention relates to improvements in heating stoves of thehot air heat radiating t pe employing a horizontal body and provicedwith means for giving the gases of combustion'a direct or an indirectcourse to the outlet flue of stove pipe.

The invention contemplates certain novel features of construction andcombinations and arrangements of parts involving the means for directingthe drafts through the stove and for heating currents of air, as

will hereinafter be more fully set forth and V claimed.

In the accompanying drawings we have illustrated one complete example ofthe physical embodiment of our invention wherein the parts are combinedand arranged in accordance with the best mode we have thus far devisedfor the practical application of the principles of our invention.

Figure 1 is a view in front elevation of a stove embodying ourinvention.

Figure 2 is a longitudinal vertical sec tional view of the stove.

Figure 3 is a transverse vertical sectional view of the stove.

Figure 4 is a top plan view of the stove, partly broken away forconvenience in showing the arrangement of vertical hot air tubes.

In carrying out our invention as illustrated in the drawings wepreferably use a rectangular shaped stove body 1 made up of suitablematerial and of ample size for various purposes, and in which thevarious parts are attached or fastened together in approved manner.

At its front the stove is provided with the usual accessories as thefire door 2 for admitting fuel as coal or wood, and the ash door 3having a damper 1, and a check damper 5 for the draft.

Within the stove body is enclosed a casing G of rectangular or oblongshape and extended longitudinally of the stove in horizontal positionwith its front and rear ends closed by the respective walls of the stovebody. Between the side Walls of the stove and the side walls of thecasing are pro- 10 which extends longitudinally of the stove body andwithwhich the two side downdraft fiues 7 and 8 communicate.

i In the upper portion of the base fine 10 is arranged a longitudinallyextended lower smoke fine 11 located centrally of the stove body. Thissmoke flue 11 is closed at its front end by the draft damper 5 whichcontrols admission of air thereto, and at its rear end the smoke fluecommunicates with the stove pipe 12 which rises from the has of thestove at the rear.

The smoke flue 11 is formed by the use of a pair of horizontal airheatingtubes 13 and 14, spaced at the sides of thelongitudinal center ofthe stove and attached at the lower face of the bottom of-the casing 63.The air heating tubes 13 and 14 both have open ends at the front andrear of the stove as indicated at 15 in Figure 1, to

permitflow of air currents therethrough for warming the atmosphere inthe room.

It will be noted tha-tby this compact arrangement of parts in the baseportion of the stove, the air heating tubes not only provide forcirculation of air in the room, but also form the side walls of thesmoke flue and these walls guide the smoke and other gases of combustionto the stove pipe 12 as indi-- cated by the arrows in Figures 2 and 3.

The fire pot 16 which contains the solid fuel is fashioned in the upperpart of the open-top casing 6, and in Figure 3 the revertible indirectcourse or draft from the fire pot is indicated by the arrows, down theside fines 7 and 8 to the base flue 10 and thence through the smoke line11, to the smoke pipe or stove pipe 12.

For a direct draft from the fire pot to the stove pipe 12, provision ismade by connecting a short smoke pipe 17 between the upper portion ofthe stove, beneath its top plate 18, and the stove pipe 12. A damper 19,having a rod 20 extended outside the stove;

is hinged at 21 to a wall of the stove body for controlling the openingto the direct draft smoke pipe 17. This damper may be opened to create adirect draft when starting the fire, or for the purpose of directlycarrying oil gases of combustion from the fire.

The fire pot is provided with a slotted sta tionary grate 22, andbeneath the grate a raking device is supported for the purpose ofcleaning or clearing the lower portion of the fuel bed in the fire pot.This device comprises a longitudinally extending, reciprocable rakingbar 23 provided with spaced cross bar 24 and the cross bar is fashionedwith per 'iendicular studs 26 for raking the bed. The ends of the crossbar are slidably supported in grooved guide plates 25 at the sides ofthe grate and the pins or studs 26 project upwardly from the cross barthrough the slots of the grate.

As the ashes are raked from the lower portion of the bed of coals in thefire pot they fall from the grate and are guided by deflecting plates 27extending longitudinally beneath the grate, to the ash pan 28 located inthe lower portion of the casing G. The pan may be removed and replacedwhen the ash door 3 is opened.

vIn addition to the horizontally extending air tubes 13 and Ll in thebase of the stove we also provide aseries of vertically disposed airheating tubes 29 at the corners of the rectangular stove body. These airtubes at their lower ends terminate in stove feet 30 and open to the airbeneath the stove base. At their upper ends the tubes terminate beneaththe top plate 18 of the stove which plate is perforated as at 31 foregress of warm air currents rising through the tubes. The air tubes inaddition to forming posts or corner supports for the stove body, thusprovide for a circulation of air in the room and assist in radiatingheat from the stove.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent isl. The combination in a heatingstovehaving an interior elevated casing to form a base line and spacedfrom the side walls of the stove to form downdraft flues communicatingwith the base line, of a pair of open end, spaced hot air tubes beneaththe casing forming a smoke fine in the upper portion of the base tine, asmoke or stove pipe con1- nlunicating with the smoke flue, and a firepot in the casing.

2. The combination in a heating stove having an interior elevated casingspaced from the side walls of the stove to form downdraft fluescommunicating with a base line beneath the casing, of a pair of openendspaced hot air tubes in the base flue forming a central smoke fine, astove pipe comn'iunicating with the smoke flue, a directdraft smoke pipeconnecting the stove above the casing with the stove pipe, and a damperfor controlling the direct draft to said smoke pipe.

In testimony whereof we aflix our signatures.
